Step-by-step explanation:
The total mass, in kilograms, of the nails the carpenter bought is 3.9 kilogram
<h3><u>Solution:</u></h3>
Given that carpenter bought 750 nails
Each nail has a mass of 
kilogram
To find: total mass, in kilograms of the nails bought
The total mass of the nails bought can be found out by multiplying number of nails bought by mass of each nail
Number of nails bought = 750
Mass of each nail = kilogram
total mass of the nails bought = number of nails bought x mass of each nail
Thus the total mass of nails bought is 3.9 kilogram
Answer:
b ≈ 7.54 cm
Step-by-step explanation:
Pythagorean Theorem
a² + b² = c²
a and b are the sides and c is the hypotenuse
hypotenuse is 11 cm
a side is 8 cm
so
8² + b² = 11²
64 + b² = 121
-64 -64
b² = 57
√b² = √57
b ≈ 7.54 cm ( use ≈ because its rounded so its not exact)
Answer:
$541
Step-by-step explanation:
Given:
The repair bill includes $355 for parts $146 for labor and a sales tax of $40
Question asked :
what is the total amount we owed = ?
Solution:
Total cost of parts to repair = $355
Total cost of labor = $146
Sales tax =$40
By adding all the cost:
Total cost of repair = $355 + $146 + $40
= $541
Therefore, total amount we have to pay = $541
50 x 50 + 100 - 43 = 2557
